Abstract: Various method, system, computer program, and business method embodiments for facilitation of renewable energy delivery using floating power purchase agreements are disclosed. In one embodiment a method for providing renewable energy for the benefit of a plurality of customers, incorporating calculations performed by at least one processor of a data processing computer environment is provided. An estimate of renewable energy provided by a renewable energy cooperative organization over a predetermined time interval is calculated based on data associated with a status of one of the plurality of the customers in the renewable energy cooperative organization. The estimate is electronically incorporated into a floating power purchase agreement (FPPA) negotiated between the renewable energy cooperative organization and an entity. The entity agrees to purchase a flexible remainder amount of the renewable energy pursuant to the FPPA.
